“螺旋耦合型慢波结构的研究”(以下简称为“研究”)一文,利用多导体传输线方法对螺旋耦合型慢波结构进行了理论分析。其中用一个简化公式计算了矩形螺旋线各段导纳与翼片导纳,进而计算了大量的色散和耦合阻抗曲线。大家知道,在多导体传输线分析方法中,导纳的计算对色散和耦合阻抗是十分重要的,尤其是耦合阻抗直接与导纳的大小成反比。通过研究,我们认为该文在计算各段导体的导钠时,假 “Spiral Coupled Slow Wave Structure” (hereinafter referred to as “Research”) article, the use of multi-conductor transmission line method for spiral-coupled structure of the slow-wave theory analysis. A simplified formula was used to calculate the admittance and the admittance of each section of the rectangular helix, and then a large number of dispersion and coupling impedance curves were calculated. As we all know, in the multi-conductor transmission line analysis method, the calculation of admittance is very important for dispersion and coupling impedance, especially the coupling impedance is directly proportional to the admittance. Through research, we think that this article in the calculation of the conductivity of each conductor of sodium, false
